The implant approach
A dental implant is a small post placed in the jaw to stand in for a tooth root. Once it is stable, a crown is attached.
The space is replaced on its own, without linking the neighbouring teeth together the way a traditional bridge often does. For some patients that is the deciding factor.
The conventional bridge approach
A conventional bridge spans the gap and is carried by the teeth on either side. Those teeth are prepared so the bridge can sit over them.
That is a meaningful trade-off when the neighbouring teeth are healthy and would not otherwise need work. It is a different calculation when they already carry large restorations.
Where an implant bridge sits between them
When several teeth in a row are missing, an implant bridge uses implants to carry a connected restoration. It replaces a run of teeth without relying on the natural teeth beside the gap.
What decides it
Bone support, gum health, bite, and medical history all influence whether an implant is recommended now, later, or not at all. The condition of the neighbouring teeth matters just as much.
Both routes are planned after an examination. Neither is universally the better option.
This comparison is general. Which approach suits a particular gap is confirmed after an examination and imaging.
